* Replace localtime() with localtime_r()Lukas Fleischer2012-11-221-5/+5
| | | | | | | | | | | | | | Since the result of localtime() is stored in a statically allocated structure, data was overwritten when a context switch occurred during (or shortly after) the execution of localtime(), potentially resulting in critical data corruption. BUG#7 and BUG#8 are likely related. This patch converts all usages of localtime() with localtime_r(), which is thread-safe.

* src/args.c: Fix bugs address in usage messageLukas Fleischer2012-06-181-12/+11
| | | | | | | | | | | * Point out that bug reports should be sent to the bugs mailing list, not to misc in help and usage messages. * Call more_info() when displaying the help message instead of copy-pasting strings to avoid double translation. Reported-by: rafael ff1 <rafael.f.f1@gmail.com> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Directly use fprintf() where applicableBaptiste Jonglez2012-05-311-12/+4
| | | | | | | | | | For some reasons, we were using snprintf() to format a string into a buffer, and then displaying this buffer to stdout using fputs(). That's exactly what fprintf() is here for, so use it. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix incorrect i18n usage for some stringsBaptiste Jonglez2012-05-251-4/+4
| | | | | | | | | | | Some strings are initialized without wrapping them in _(); instead, _() is applied on the variable when it is used. This is incorrect, since these strings don't get added to the catalog. Fix that by applying _() only once, when the string is declared.

* Switch to Linux kernel coding styleLukas Fleischer2012-05-211-636/+541
| | | | | | | | | | | | | | Convert our code base to adhere to Linux kernel coding style using Lindent, with the following exceptions: * Use spaces, instead of tabs, for indentation. * Use 2-character indentations (instead of 8 characters). Rationale: We currently have too much levels of indentation. Using 8-character tabs would make huge code parts unreadable. These need to be cleaned up before we can switch to 8 characters. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Document removal of the "-N" command line optionLukas Fleischer2012-05-171-4/+1
| | | | | | | This option was removed in 6b95f7b67dc8e29072fed4e05efa450422661348. Update the usage message, the man page and the manual accordingly. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Declare several parameters/variables constantLukas Fleischer2012-05-081-6/+7
| | | | | | | | | | | | Add the "const" keyword to parameters and variables that are never modified. Most of these were spotted by "-Wwrite-strings". We cast the second parameter to execvp() explicitly as it expects a "char *const[]" where it should expect a "const char *const[]" (according to the documentation, this is due to compatibility reasons). This should be changed once we come up with a better solution. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/args.c: Add "void" in some function declarationsLukas Fleischer2012-05-081-4/+4
| | | | | | | | | These functions don't take any parameters, "void" is the right parameter signature to use here. Fixes some warnings seen with "-Wstrict-prototypes". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Add a read-only optionLukas Fleischer2012-02-241-1/+6
| | | | | | | We don't save any configuration nor items if this is set. This should be used with care, and hence there's no short option for this. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Extract config file handlers into a separate fileLukas Fleischer2011-12-091-2/+2
| | | | | | | | We used custom_load_conf() to load the configuration file and io_save_conf() to save configuration. Move these functions, including all helpers, to a central location. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/args.c: Remove obsolete "-N" flagLukas Fleischer2011-11-141-4/+0

* src/args.c: Allow for specifying custom format stringsLukas Fleischer2011-11-141-23/+66
| | | | | | | | | | | | | Following long command line options can be used to override the default format strings: * --format-apt * --format-recur-apt * --format-event * --format-recur-event * --format-todo Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* print_*(): Add format specifier to print notesLukas Fleischer2011-11-141-70/+9
| | | | | | | | | | | | * Move print_notefile() from "src/args.c" to "src/utils.c". * Add a "%N" format specifier to print_*(). This invokes print_notefile() and prints the content of an item's note file. * src/args.c: Use the new format specifier instead of print_notefile() everywhere. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a dynamic method to print todo items to stdoutLukas Fleischer2011-11-141-13/+7
| | | | | | | | | | | | This goes in line with the other commits adding print_*() support. Following format specifiers are allowed: * p: Print the priority of the item * m: Print the description of the item * n: Print the name of the note file belonging to the item Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a dynamic method to print recurrent items to stdoutLukas Fleischer2011-11-141-7/+3
| | | | | | | | | Add print_recur_apoint() and print_recur_event() helper functions to print recurrent items to stdout and use them everywhere. Currently, these are only wrapper functions to print_apoint() and print_event() that create temporary, non-recurrent items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a dynamic method to print events to stdoutLukas Fleischer2011-11-141-3/+1
| | | | | | | | | | | | | Add a flexible helper function print_event() and use it whenever we print events to stdout. This reduces the number of copy-pasted code and eventually allows for specifying custom format strings. Following format specifiers are supported: * m: Print the description of the item * n: Print the name of the note file belonging to the item Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use a dynamic method to print appointments to stdoutLukas Fleischer2011-11-141-18/+2
| | | | | | | | | | | | | | | | | | Add a flexible helper function print_apoint() and use it whenever we print appointments to stdout. This reduces the number of copy-pasted code and eventually allows for specifying custom format strings. Following format specifiers are supported: * s: Print the start time of the appointment as UNIX time stamp * S: Print the start time of the appointment using the "hh:mm" format * d: Print the duration of the appointment in seconds * e: Print the end time of the appointment as UNIX time stamp * E: Print the end time of the appointment using the "hh:mm" format * m: Print the description of the item * n: Print the name of the note file belonging to the item Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Use a global configuration variableLukas Fleischer2011-11-141-30/+28
| | | | | | | This is one of the few valid use cases for a global variable. No need to make it pseudo-local and pass it from one function to another. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Remove parentheses from return statementsLukas Fleischer2011-11-021-2/+2
| | | | | | | | | | | | | | No reason to use "return (x);" here. Refer to the GNU coding guidelines for details. Created using following semantic patch: @@ expression expr; @@ - return (expr); + return expr; Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Make use of the NULL macroLukas Fleischer2011-11-021-16/+16
| | | | | | | | | | | | | | | Use this constant everywhere when referring to a null pointer instead of casting 0 to various types of pointers. Created using following semantic patch: @@ type type; @@ - (type *)0 + NULL Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not cast unused return values to voidLukas Fleischer2011-11-021-13/+13
| | | | | | | | | | | | | | | | | | | | A small style fix that removes all remaining "(void)" casts. Using these isn't encouraged in GNU coding guidelines and doesn't serve a certain purpose, except for satisfying a few static code analysis tools. We already nuked some of these in previous patches, but this semantic patch should fix what's left: @@ identifier func; @@ - (void)func ( + func ( ...); Long lines were re-formatted manually.

* Avoid use of printf()/fprintf()Lukas Fleischer2011-11-021-1/+1
| | | | | | | | | | | | | | | | Use one of the following functions where appropriate: * puts() (whenever we print hard coded strings to stdout) * fputs() (whenever we print hard coded strings to a stream) * putchar() (whenever we print a single character to stdout) * fputc() (whenever we print a single character to a stream) * strncpy() (whenever we copy hard coded strings to a buffer) This removes the overhead introduced by the format string parser and reduces the number of false positive C-format strings spotted by xgettext(1)'s heuristics. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Avoid unnecessary start time calculationsLukas Fleischer2011-10-211-1/+3
| | | | | | | | | | | | | | Rename recur_*_inday() to recur_*_find_occurrence() and use the new functions whenever we actually care about the start time of an occurrence. Reintroduce recur_*_inday() as wrappers to recur_*_find_occurrence() and pass NULL as start time buffer (which means "skip start time calculation"). Keep using these when we only want to know if a recurrent item belongs to a specific day but do not care about the actual start time. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Add command line argument to run the GC manuallyLukas Fleischer2011-10-051-2/+21
| | | | | | | | Adds a "-g" option that allows for running the garbage collector for note files manually. This is useful for users that do not use note files at all or rarely edit/remove them. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

| * Fix sort order in app_arg()Lukas Fleischer2011-07-301-52/+78
| | | | | | | | | | | | | | | | | | | | | | | | We used to iterate over the list of regular appointments and the list of recurrent appointments in separate loops, thus leading to recurrent appointments being printed first and regular appointments being printed afterwards, regardless of their start and end times. Merge these loops to coerce precedence of the start time. There's still a fair bit of hackery in here - we will fix that later. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

| * Invoke vars_init() before importing data with "-i"Lukas Fleischer2011-07-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | We forgot to call vars_init() when importing an item using the "-i" command line argument, which led to the pager configuration variable being unset and hence the pager invocation (triggered to show the log in case there are any errors during import) failing. Fix this by calling vars_init() before io_import_data(). Reported-by: Andraž 'ruskie' Levstik <ruskie@codemages.net> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
